Kaiser Permanente Largo Medical Office Building – Largo, MD Christopher Pozza Technical Assignment1 September 21, 2012 Advisor – Rob Leicht Tech 1 Kaiser Permanente Largo Medical Office Building Executive Summary Technical Assignment 1 includes an investigation of the building construction, systems utilized and scope of work required for the Kaiser Permanente Largo Medical Office Building. This report goes into detail about the project schedule, cost evaluation, existing conditions, project delivery and more. Results of this investigation are discussed in more detail throughout this report. The Kaiser Permanente (KP) Largo Project includes expansion of the existing medical office building with a combination of both minor and major renovations to the occupied medical office building. The addition will consist of three-story, 106,700 square foot. The goal of this project is to implement requirements of the KP functional program to meet the current and future patient health care demand as well as create a healthier experience for patients and staff. The three-story addition footprint is replacing a large amount of parking space, so a four-level parking garage was built before the focus of this report could begin. Scope of the addition is shown in Table 1.

The schedule has very little room for delay and has been strict ever since the start of construction. DPR was awarded this construction contract on December 27, 2010. The Notice to proceed was issued June 10, 2011 as design and preconstruction was underway; however, construction was actually delayed right away due to obtaining the owner provided building permit. Once obtained, site mobilization began followed by construction with some unique sequencing of activities discussed later in this report. First patient for the addition is expected July 17, 2013. The cost analysis has been dissected slightly for a more accurate analysis. The addition is the key focus of the cost comparison using RSMeans. The actual building cost of the addition is $230.79 per square foot. This was almost $100 per square foot more than the RSMeans square foot analysis. There are several reasons for this large difference. This project is not a typical medical office building, serving as more of a hospital with larger than average and more unique systems in some cases. Further detail will be provided in the Project Cost Evaluation section. Some ideas for further research include comparing the chosen masonry façade to using precast panels instead to cut schedule time, how BIM was used with preconstruction planning and its affect throughout construction and whether or not the building’s structural steel system selected was the most cost effective choice for a medical office building.

Kaiser Permanente Largo Medical Office Building Tech 1 Project Schedule Summary Kaiser Permanente has developed a well-planned execution of expanding its current facilities in Largo, MD. Because the new addition will take up critical parking areas, a new four-story parking garage was completed before the addition construction would start. Upon completion of the parking garage, DPR was awarded the construction contract to be the general contractor on December 27, 2010. Kaiser Permanente issued the Notice to Proceed on June 10, 2011. A more detailed schedule, the Project Summary Schedule, can be found in Appendix A. DPR is responsible for construction of the addition along with the renovation of the existing medical office building. The Project Summary Schedule does not include any renovation work as planning is still underway and construction is not to start until the addition is complete. This schedule is broken in three main categories; Design and Procurement, Construction and a Closeout & Occupancy phase; each including major milestone dates throughout the duration of the project. One of the biggest challenges this project presents is dealing with an occupied building. Specific design requirements had to be met due to the existing building and its architectural features which will be investigated more in depth in Technical Assignment 2. However, because of the site layout, it has been determined that major work would flow best from the area closest to the existing building and proceed south to the rest of the L-shaped addition, as seen in Figure 1 and starting in Area B proceeding to Area C. After completion of the addition, it has been determined the renovation will be phased while occupied night work will be required in four 10-hour shifts. The Construction Phase was actually delayed from the start due to delay attaining the Owner provided permit. Site mobilization and utility work could begin, but foundations were not able to start until the end of August 2011. Construction includes a fairly traditional route with a few variations discussed in further detail to come later in this analysis. A few unexpected variations include structural steel beginning before a slab on grade begins, drywall finishing within a couple weeks of finishing 3rd floor windows, and the overall roof sequencing. The Closeout & Occupancy Phase has been broken into the Startup & Commissioning activity, which summarizes entails several inspections and Figure 1 - Footprint of the existing building and addition, separated into punchlist completions. Along with Startup & different areas based off construction. These references will be used throughout the report. Image created by Chris Pozza. Commissioning and Owner Furnish Contractor Install (OFCI), three major milestones have been included. Substantial Completion is set for February 11, 2013. Final Completion follows on April 12, 2013. There is an activation period lasting a few months before the first patient can receive treatment on July 17, 2013. It is intended that the renovation will be complete in one year from time of the first patient of the addition. Technical Assignment1 | September 21, 2012 3 Kaiser Permanente Largo Medical Office Building Tech 1 Foundation After necessary underground utilities are dealt with and completed, the foundation can start. Primarily, spread footings are used. The sequence began with the framing, reinforcing and placement of the footings followed by perimeter foundations. The sequence began in Area B, quickly moving to Area C. Footings are normal weight, 3,000 PSI with a slump of 3-4” and extend to at least 2.5’ below the final exterior grade, safely below the frost line. The slab on grade actually began after structural steel, which will be discussed more in the next section. The slab on grade is 5” thick, 3,000 PSI normal weight concrete reinforced with W2.9xW2.9 welded wire fabric. The system rests on 15 mil vapor barrier over 4” of compacted stone aggregate. The slab was finished with a smooth, trowel finish. The only area of slab to differ is below the MRI room. Here the slab is required to be 16” thick, 3,000 PSI normal weight concrete and reinforced with 5/8” diameter fiberglass reinforcing. Dewatering systems were deemed unnecessary as the closest level groundwater was encountered at was 12’ below the surface. Wooden formwork was used where necessary and for all housekeeping pads required in the structure. Structure Because the new footprint is an L shape, steel began near the existing building, referred to as Area A. The structure itself is comprised of steel columns, girders and beams. Sequencing could repeat the same direction as foundations; moving south to Area B and finishing steel erection with Area C. It should be noted that the steel sequence was changed near scheduled time of erection. Originally, the steel erection plan was to place all columns on the first level, which are two-story columns, followed by the entire top level; again moving from Area B to Area C. This was noticed and quickly changed by the project team because if the original sequence were to take place, valuable time would have been lost. Slabs and floor deck would not have been able to begin working in areas if crane lifts were going to be done overhead, so the sequence was changed to do entire areas of the building instead of entire floors. Slab on grade construction was able to start roughly one week after steel erection began. A unique aspect of this project is the structural steel connections. A Sideplate Frame System, seen in Figure 2, has been selected. This is much more popular on the west coast, not traditionally being done on the east coast. This system will be discussed in more detail in the Structural Steel section to follow. Figure 2 – Photograph of a Sideplate system. This is a moment frame that connects columns to beams and girders and can be single or double sided, shown above is a double-sided connection. Spray-on fireproofing has already been applied to the structural steel at this point of construction. Personal photograph taken by Chris Pozza. Metal deck placement began the day steel erection completed to be followed by installment of shear studs, working from the bottom up. A 60-ton Technical Assignment1 | September 21, 2012 4 Kaiser Permanente Largo Medical Office Building Tech 1 crawler crane was used and laydown areas will be discussed more in this analysis. A more detailed schedule analysis and estimate for steel will be developed in the following Technical Report 2. Finishes The building finishes sequence includes numerous activities; started with insulation and hanging of drywall. Other activities included are taping & finishing drywall; first coat paint; installing the ceiling grid, light fixtures, sprinkler heads and final paint. Once the final layer of paint is completed, a close-in inspection will take place. There are a few things to point out regarding the sequencing of events during construction and how they affected finishes. The exterior enclosure was behind schedule from early on due to obtaining the owner provided building permit late and weather delays. Along with this, complicated details for the vapor barrier further hindered the façade construction about one month. Surprisingly, MEP & Fireproofing rough ins started on the first floor the same day the exterior enclosure started. Along with this, a temporary roof was necessary to be tied down. This combination delayed the Building Watertight milestone and major elevator work. A low roof in Area C was required to have a temporary roof because a Mason King system was required to be placed on it for masonry work. Owner Furnished and Contractor Installed (OFCI) equipment will start arriving on site on October 30, 2012. Substantial Completion is expected to be February 11, 2013. Final Completion for the addition is scheduled for April 12, 2013 and First Patient will be July 17, 2013. Once construction ends in the addition, it will begin the phased construction of the occupied existing medical office building. The renovation is currently expected to take one year to complete. Technical Assignment1 | September 21, 2012 5 Tech 1 Kaiser Permanente Largo Medical Office Building Building Systems Summary The building systems primarily focused on in this section are the structural steel frame, electrical system, masonry and glass curtain wall systems. The structural steel frame has unique connections and could provide an interesting comparison in later analyses whether or not the system selected was cost effective. The electrical system is critical for a medical office building where people’s lives could depend on the building’s power. System redundancy is required with backup power in case of emergency. Finally, the exterior façade is mostly covered in brick veneer and a prefabricated aluminum curtain wall. The brick veneer could possibly be studied closer with an alternate precast system instead. Yes No Work Scope Demolition Structural Steel Frame Cast-In-Place Concrete Precast Concrete Mechanical System Electrical System Masonry Curtain Wall Support of Excavation Table 2 - Building Systems Summary table created by Chris Pozza. Demolition Prior to start of construction, the existing surfaces, structures, paving and hardscape making up what was once a parking lot needed to be removed. A vestibule connected to the existing pharmacy needed to be demolished as well as a canopy at the loading dock. There are several locations where the addition connects to the existing building that will need to be opened in order to create corridors connecting the two structures. This will be done as construction progresses more. Once the renovation begins, there will be large amounts of demolition in the existing building as entire departments are being redone or moved. Zip walls will be required in areas during renovation work in order to limit the amount of dust and debris reaching neighboring areas. Being that this building was constructed in 1998, asbestos and lead are not to be a concern. Excavation There is no major excavation that required an additional form of support as this three-story addition’s first floor is a slab on grade with no basement. Minor excavation is required for the footings and foundations, underground utilities and an oxygen tank. Utility trenches have been dug four inches deeper than the required bottom-of-pipe elevation to allow for a layer of aggregate bedding. Because the water level was well below foundations with only shallow excavations being done, no dewatering systems were necessary. Technical Assignment1 | September 21, 2012 6 Tech 1 Kaiser Permanente Largo Medical Office Building Structural Steel Frame The main superstructure consists of wide flange beams, columns and girders. The first floor is a 5” thick concrete slab on grade. The rest of the building’s floor deck is 3” deep, 18 gage, composite metal deck with a 2.5” topping thickness. Typical floor beams range from W16x26 to W16x31 with girders ranging from W21x57 to W21x73. Typical roof construction consists of 3” deep 20 gage steel roof deck. Decking has been specified based on a three span condition. Wide flange beams are used on the roof that primarily consists of W14x22, but W21x44 are required where supporting rooftop mechanical units. Roof girders mostly range from W21x44 to W21x62 with W18x40 and W18x50 spanning the perimeter. Hollow Structural Steel (HSS6x6x1/4) is used near the cobrahead roof. Steel is sloped toward roof drains. This structure uses a unique moment connection, a Sideplate Frame System, which is shown to the left in Figure 3. Figure 3 - Field erection method of a Sideplate Frame System. Image courtesy of Ellerbe Becket. Figure 4 - 3D drawing of a Sideplate Frame System. Image courtesy of Ellerbe Becket. Sideplate connections were chosen over braced frames because they allow lateral framing to be located more conveniently and offer a greater cost economy. This system has previously been used on Kaiser Permanente facilities on the west coast. Figure 4 shows a 3D view of a side plate. Connections are prefabricated and require minor field work to bolt and weld members. The system itself is a beam-to-column moment connection. This can be a one- or two-sided connection that saves space and construction time. A shear plate is welded to the web of the column above and below the physical side plate with one Technical Assignment1 | September 21, 2012 7 Tech 1 Kaiser Permanente Largo Medical Office Building on each side. The side plate itself extends beyond the column where the beam is then placed and bolted. Seen below in Figure 5 is an elevation and plan view of the Sideplate Frame System. Figure 5 - Elevation and plan view of a Sideplate Frame System. Image courtesy of Ellerbe Becket. Cast-In-Place Concrete Cast-in-place concrete served several purposes for this structure. Shallow spread footings make up the foundation. The floor systems, including the 5” thick slab on grade, are all cast-in-place that are reinforced with welded wire fabric. Housekeeping pads are also required for all mechanical, electrical and plumbing equipment to elevate equipment. The screen wall at the west loading dock were cast-inplace concrete as well. A concrete pump truck was utilized to place the majority of concrete placement. Buggies were necessary for small placements such as housekeeping pads. Technical Assignment1 | September 21, 2012 8 Kaiser Permanente Largo Medical Office Building Tech 1 Precast Concrete Although the neighboring parking deck is predominantly brick-clad architectural precast, the addition uses very little precast; however, precast concrete was used as an architectural feature to make a smooth transition from the existing to new structure. This accent band can see going in place in Figure 6, along with the vapor barrier, insulation and necessary steel tiebacks. The band itself is called out in red below in Figure 7. It can be seen that a color near that of the brick used blends nicely with the window sills and accent bands. An all-terrain forklift was used to lift precast to Fraco Lifts from which pieces are placed. Figure 1, Below - Architectural precast concrete is seen under window sills and spanning the addition on the left above the third story windows. Personal Photograph taken by Chris Pozza. Figure 6 - Precast concrete can be seen above which make up the accent band along with east elevation. Personal photograph taken by Chris Pozza. Architectural Plant-cast Concrete Mechanical System Four rooftop air conditioning units resting on 30” high roof curbs will be responsible for the building’s air conditioning. Imaging and MRI suites will have smaller dedicated split air conditioning units. New terminal units with electric reheat coils will be included with variable air volume (VAV) and constant air volume (CAV) units, which will be the primary source of heating. Direct Expansion rooftop units with supply and return fans will be included on the addition as well. These are equipped with variable frequency drives (VFDs). Chillers will be closed-loop systems that use non-CFC/HCFC R404a refrigerant. The main mechanical and plumbing room is in the southwest of Area C. All rooftop air conditioning units will have two banks of filters, along with economizing dampers and controls to provide free cooling when outdoor conditions are suitable. A few other energy conservation measures will be taken for this Technical Assignment1 | September 21, 2012 9 Kaiser Permanente Largo Medical Office Building Tech 1 system. Operating suites have setback controls for unoccupied periods and the mechanical system controls will provide and optimize energy efficiency. All rooftop air conditioning units will have VFDs at every supply and return fan allowing for variable airflow. A direct digital Energy Management System (EMS) will optimize units operation. A unique feature is the cryogen vent which is required for the MRI equipment. This vent allows the superconducting liquid, used to keep magnets from overheating, to be dissipated from the building in the event of an unexpected shutdown, also known as a quench. The vent runs from the MRI suite through the building’s partition walls until exiting the building on the roof. A 6” fire and domestic water service lines will be split from the service provider to supply this building. A Double Check Valve backflow preventer will be provided in the fire main supplying the 50 horsepower fire pump. The fire pump serves two standpipes in risers. Every floor will have a sprinkler branch, control valve, tamper switch and a flow switch that are connected to the fire alarm panel. Concealed sprinklers will be provided for public spaces and pendent type sprinklers will be located in ceilings of patient and administrative rooms. A dry-pipe sprinkler system will be provided for the main patient entrance canopies. Electrical System Pepco Power is the electric utility supplier to the existing building. The three-story addition is going to include a service yard on the southeast corner of the building. The electrical system’s service connects to a Pepco Power supply that consists of a 13.2 kV feeder serving a utility provided 480/277 Volt Pad mounted transformer, which will be fed from two sources in a three-way, concrete-encased ductbank. There will be a one-way concrete encased ductbank running to an existing Pepco Pole. A two-way concrete-encased ductbank will also be connected to a new Pepco power source. From the service yard, a connection will be run by Pepco Power to the main switchboard which will consist of a 15-way concrete-encased ductbank. Also in the service yard are two 1,250 KW Diesel generators which are connected to the addition’s paralleling gear. Between the paralleling gear and Switchboard MDS are eight main circuit breakers (MCB) and a fire pump; each of which have an automatic transfer switch to transfer the emergency distribution system loads from the Pepco Power source to the emergency generators. The main switch board and paralleling gear are both 4,000 Amp, 480/277V, and three-phase. Dry-type transformers are typically found throughout the building in electric rooms, ranging in size from 45 to 150 KVA, with the most common being 75 KVA. The main electric room is adjacent to the main mechanical room in the southwest corner of Area C. There are several smaller electric rooms on floors two and three. The building uninterruptible power supply (UPS) for the addition will operate in union with the existing building’s electrical system. Its purpose is to provide back-up and distribution for critical electrical loads. The system is comprised of a single 60 KVA, 54 KW UPS module. Also included is battery capable of a 15-minute run time at this load. Technical Assignment1 | September 21, 2012 10 Kaiser Permanente Largo Medical Office Building Tech 1 Lighting A three-phase, 277V, 20 KVA UPS System with a 90 minute battery back-up will be specifically for emergency lighting applications. 277V, 3500/4100 Kelvin fluorescent fixtures dominate the new addition although there are some 120V incandescent fixtures used in areas for special use or decorative applications and include dimmers. The predominant luminaire in corridors, offices and patient rooms will be 2’ by 4’ recessed ceiling fixtures with either two or three 32 watt T8 lamps. Waiting areas and imaging rooms are generally comprised round recessed LED fixtures. The MRI room will use 200 watt down lights actually running off of DC power specifically rated for MRI suites. Exterior lighting is mainly comprised of 100 watt HID lensed downlights are recessed in the exterior canopies on the east and south ends of the addition. Masonry Non-load bearing brick veneer over steel studs will be the primary building façade. There are two colors of brick used that match the existing building’s colors. Working from the inside out, the wall has 5/8” gypsum board on the interior of 6” metal studs and batt insulation. There is a ½” layer of gypsum sheathing, air/vapor barrier, 2” rigid insulation tight to the air barrier, followed by a 2” air space before reaching the exterior brick. Figure 8 - Detail of exterior masonry wall at foundation. Image courtesy of Ellerbe Becket. Fraco Lifts were set up around the perimeter of areas placing brick. MasonKing lifts were required in areas where veneer work was done above rooftops, which are shown and described below in Figures 9 and 10. Figure 9 - View looking at southwest elevation. A MasonKing lift is required in areas where work is done above rooftops. These lifts have to be simultaneously cranked by hand to be lowered or raised. Personal photograph taken by Chris Pozza. Figure 10 - View looking at east elevation. Fraco Lifts are used around exterior to provide efficient flow of construction along a large percentage of elevation at a time. Materials are lifted into place with a boom lift. Personal photograph taken by Chris Pozza. Technical Assignment1 | September 21, 2012 11 Kaiser Permanente Largo Medical Office Building Tech 1 Curtain Wall Prefabricated aluminum curtain wall systems are used mostly on the west and south elevations. This wall system consists of 2.5” wide by 8” deep exposed mullions and caps at multistory locations. At low rise locations, 2.5” wide by 6” deep exposed mullions and caps are used. There are horizontal and vertical expressed caps along with the two main types of glass; 1” clear low E coated insulated glass and 1” spandrel glass. The system is thermally broken and designed to accommodate horizontal and vertical Figure 11 - View of west elevation curtain wall system under construction. movement. The boom lift used during construction of the façade system can be seen at the bottom of the photo. Personal photograph taken by Chris Pozza. An exterior view of glass curtain wall going in place is shown above in Figure 11. To the left is Figure 12, an interior view looking at the same area on the second floor is seen. Eventually, this area will be a corridor into the existing building (straight ahead) with waiting areas to the right, getting plenty of natural daylight. Figure 12, left – Interior view of west elevation curtain wall system under construction. Personal photograph taken by Chris Pozza. Exterior Insulation and Finish System (EIFS) An EIF System over steel stud back-ups is used primarily on the underside of overhangs and screenwalls around rooftop units. Primarily, it’s used in areas where it actually cannot be seen. At non-insulated soffit locations, EIFS is applied directly over the water resistant sheathing. The EIFS will have an acrylic finish coat with a standard light-sand, troweled finish. The color has been chosen to match the EIFS in the existing building. Technical Assignment1 | September 21, 2012 12 Kaiser Permanente Largo Medical Office Building Tech 1 Metal Panel There are three types of metal panel used on this project. Insulated Aluminum Panels (MP-1) are 2” thick insulated metal panels that are bonded to factory foamed-in-place core with a tongue-and-groove joint. Composite Aluminum Panels (MP-2) are comprised of two sheets of aluminum sandwiching a core of extruded thermoplastic. This system is formed in a continuous process with no adhesives between unlike materials. Preformed Exposed Fastened Metal Panels (MP-3) are fabricated from zinc-coated steel. These will largely be used at the elevated roof of the clerestory shown below in Figure 13. Sustainability Features Although this building is not going to be LEED certified, there are many sustainable features in this medical office building. Construction is guided by the Green Guide for Health Care, although contracts are not tied to it. Throughout construction, material is being separated and recycled. A major passive feature of this building is the large cobrahead roof on the third floor of the addition which spans over 200 feet in length, shown in Figure 13. This will bring in large amounts of natural daylight without overheating the space. The top layer of roofing consists of a thermoplastic membrane. This is a durable material that, because of its white color, will help the roof reflect light and absorb as little heat as possible, preventing the heat island effect. Figure 13 - Shown above is the clerestory that stretches over 200 feet long and bringing in natural light. Personal photograph taken by Chris Pozza There will also be a drainage pond located between the Area C and the existing south wing. The pond will manage storm water runoff and help improve the water quality of nearby sources. Another great thing incorporated into the landscape design is the natural vegetation that will be used surrounding the building. There is a lot less macadam and concrete around the perimeter of the building, allowing plenty of space for grass, shrubs and small trees native to the area. The area surrounding the building, once completed, will have entirely new pathways guided through a variety of vegetation. The plantings have specifically been chosen for their indigenous characteristics and don’t require more water than the natural environment provides; therefore, an irrigation system is not required. Technical Assignment1 | September 21, 2012 13 Tech 1 Kaiser Permanente Largo Medical Office Building Project Cost The following section focuses on the cost of the KP Largo Medical Office Building. The key focus of this section will be the cost of work in the addition. The renovation will not be focused on in great detail because it is still in a planning stage and it will not be a traditional sequence or full-building renovation with any comparison cases to compare to in the area that would be relevant. Information about the addition and renovation will be included to show relative cost information, but the square foot and assemblies estimates will only include addition work as this makes up over 80% of the total project cost. Project Cost Total Project Cost Addition Renovation Size (Square Feet) 236,200 106,700 129,500 Cost ($) 39,558,519 32,504,687 7,053,833 Cost per Square Foot ($) 167.47 304.64 54.47 Table 3 - Total project cost and size information for the Kaiser Permanente Largo Medical Office Building. Table created by Chris Pozza. As noted above in Table 3, the guaranteed maximum price is $39,558,519. The total cost per square foot is very low for such a project, but that is due to renovation work typically being lower and only certain areas in the existing building being renovated. The addition costs roughly $305 per square foot. Actual Construction Cost Total Actual Const.

Key assumptions used in estimate: Building Type – Medical Office, 2 story (best match) Data Release – Year 2011 Quarter 2 (Final GMP Release date) Wall/Framing Type – Face Brick with Concrete Block Back-up/Steel Joists Perimeter - measured to be 1,010 feet Story Height – 13.33 feet (average taken of all three) Contractor’s Fee – 1.95% in GMP Contract Location Adjustment – Silver Spring, MD Cost Comparison KP Largo MOB Addition RSMeans CostWorks Estimate Cost ($) 24,625,461 14,174,500 Cost per Square Foot ($) 230.79 132.84 Table 6 - Cost Comparison between RSMeans CostWorks estimate and the actual cost of this project. There were several factors that led to this building’s RSMeans comparison being much less than the actual price. To start, the closest match was a 2-story medical office building. Although the story count and height was adjusted and increased, the estimates were still very low. The most obvious, as seen in the Square Foot Estimate found in Appendix B, was the assumption of the shell. CostWorks provided $1,747,500 for the Shell. This included floor and roof construction; exterior walls, windows and doors; Technical Assignment1 | September 21, 2012 15 Tech 1 Kaiser Permanente Largo Medical Office Building and roof coverings and openings. This building was largely a masonry façade. The actual masonry cost itself was $1,131,376. With such a large footprint and building perimeter, there are extensive underestimates. A very large portion of actual building cost was finishes, at over $4 million. RSMeans estimates wall, floor, and ceiling finishes to be under $1.5 million. The last obvious major difference between estimates is the HVAC and Electrical systems. CostWorks groups elevators and lifts; plumbing fixtures; terminal & package units; electrical and lighting systems; and communication systems together to total $7,546,000. Electrical systems alone in the Largo Medical Office Building cost $6,008,686. Uninterruptible power systems and system redundancy contributes to very high electrical costs, but there are definitely more major scope busts in the RSMeans estimate. One thing to take note of is the fact that RSMeans did include a contractor’s fee (1.95%). The actual construction cost calculated above in Table 2 does not include this fee, making the difference between estimates even larger. Assemblies Cost Estimate An assemblies estimate was conducted to compare the building’s MEP system to the actual costs were. As noted in Table 5, mechanical and plumbing systems were grouped together the same as the actual construction estimate that was done. There are several reasons for the large variance between estimates. Many of the systems were tough to match due to the exact systems not being provided by RSMeans, so the closest to actual component was chosen. Assemblies Cost Comparison KP Largo MOB Addition RSMeans CostWorks Estimate Electrical ($) 6,008,686 4,488,442 Mechanical and Plumbing ($) 5,158,880 3,652,492 Table 7 - Assemblies cost estimate compared to the actual estimate. Table created by Chris Pozza. Because of the complexity of the electrical system, system redundancy and oversizing in case of emergency will make the actual cost rise dramatically. Also, systems including headwall units, nurse stations, elevators, MRI and imaging equipment were not included in the RSMeans estimate. At the same time, some things like branch wires were only partially included in estimates where realistically the lengths and quantities are much larger. The mechanical and plumbing systems estimate also had a large difference. Some contributing factors to the lower amount are the absence of medical gas and equipment, ductwork and diffusers. A few key assumptions made included all lighting fixtures as being fluorescent tubes, all variable-air volume boxes are the same size and each floor has 14,000 linear feet of 20 A wire.

Technical Assignment1 | September 21, 2012 16 Tech 1 Kaiser Permanente Largo Medical Office Building Existing Conditions The Kaiser Permanente Largo Medical Office Building is found in Largo, Prince George’s County, Maryland. This building is less than two miles away from FedEx Field, home of the Washington Redskins. Between the football stadium and site is Interstate 495. Directly to the west of the site is Landover Road, Route 202. These major roadways allow for several means of access to the site in a relatively short distance. N Figure 14, above right – Zoomed out site view highlighted in red showing major nearby access routes such as Interstate 495 and Route 202. Image taken from maps.google.com. The site is surrounded almost entirely by roads. Technology Way is to the north, Mercantile Lane to the west and Landover Road to the east. Directly to the south is the only area where commercial property can be accessed directly. The terrain is flat and relatively level as the majority of the space was previously a parking lot for the existing building. N Figure 15, right – Zoomed in site view of the existing medical office building highlighted in yellow. The majority of the site surface is hardscape for vehicle and pedestrian traffic. Due to the outdated image, the existing parking garage was drawn in blue. Neighboring low-rise buildings can be seen a large distance away, thus construction will have minimal impact on neighboring buildings. Image taken from maps.google.com. It can be seen that buildings in this area typically have a large footprint and are relatively low, ranging from two to four stories. KP’s medical office building is no different, actually being one of the tallest at four stories and 51’ 4”. It can see in Figure 15 that the majority of the site is parking lot, even though the image is outdated due to the current parking garage which has been added, highlighted blue. A more detailed site plan showing the existing conditions has been created. Please refer to Appendix D. Underground electric below the existing parking lot to be removed is included. One unique thing is that many of the existing utilities near the new building footprint have been added during the construction of the parking garage in preparation for this project. Once excavation begins for the addition, trenches and utilities will have much less of an impact on the overall site. Technical Assignment1 | September 21, 2012 17 Kaiser Permanente Largo Medical Office Building Tech 1 Site Layout Planning Excavation & Site Mobilization A temporary bypass road has been placed adjacent to the south entrance of the existing parking garage. The majority of the existing parking lot has been demolished for the new building footprint. This, with a legend and detailed plan can be seen on the Excavation & Site Mobilization plan found in Appendix E. Deliveries will still be made to the east loading dock of the existing building for occupants. A temporary trap is located south of the bypass road to catch water runoff from the large building footprint. Parking is available for the project team, small at this time, near the site trailers. Temporary power will enter the site from a Pepco utility pole connecting to a power shed near the trailers. This will remain in place the duration of construction. Other utilities can be seen in their respective trench areas. The recent construction of the parking garage included placing utilities where necessary for the new addition. This helped limit the amount of utility time and space needed. Excavation began near the existing building and moved towards the southwest end of the site. A mock-up area has been designated between the bypass road and parking garage. Here, a mock-up of brick veneer including a window to show joints and connections will be fabricated. Dumpsters are placed near the southwest corner of site as well. Access to the new parking garage is still available near the mock-up area; however, this area is not barricaded so pedestrians are able to walk around the parking garage between the site fence and garage. Structure There are three major entrances to site, along with two pedestrian gates for workers. Additional parking is provided for construction workers in the neighboring parking garage. The third level ramp continuing to the fourth level can be utilized by the workforce, which requires about 55 spaces maximum. Large laydown areas are utilized between site entrances on the site and the northwest corner. A 60-ton crawler crane was used for steel erection. The laydown area for steel sequence #1 was between Area A and the site trailers. Steel was taken from the truck and placed in the laydown area where material could then be picked by the crane. Sequence #2’s laydown area was in the southwest corner of Area C. Overhead protection was also required near the existing building exit on the east elevation due to crane picks. Night work actually had to be done for about a week in Area B, near the existing MRI room. This area is labeled on the Structure Plan in Appendix E. Crane picks could not be done overhead during the day while the MRI was in use. The site trailers with appropriate parties involved are also labeled in more detail. Technical Assignment1 | September 21, 2012 18 Kaiser Permanente Largo Medical Office Building Tech 1 Finishes Masonry has been included on the Finishes Plan due to the major masonry façade work happening simultaneously with interior work. Fraco Lifts are shown along almost the entire east and south facades to provide the most efficient brick placement possible. The interior follows the same area sequencing as the foundations and structure, from north near the existing building to the southwest. Two façade locations have been left open intentionally to allow materials to be lifted into and removed from the building. The opening at the south is also a pedestrian access entrance on the first level. Here, overhead protection is required. All-terrain forklifts were used on site to lift masonry material to scaffold and MEP material to the upper floors. The loading dock has been moved as shown in the last site plan, the Finishes Plan in Appendix E. This decision was due to the site being very active during this phase and the existing medical office building gets several deliveries daily. Technical Assignment1 | September 21, 2012 19 Kaiser Permanente Largo Medical Office Building Tech 1 Local Conditions Geotechnical Report The geotechnical analysis and study was conducted by Hills-Carnes Engineering Associates, Inc. Their work was reported on August 27, 2010. This date was prior to even the new parking garage on site which was complete before the addition started, so the soil analysis was done on a much larger area than just the surrounding footprint of the addition. In total, 28 Standard Penetration Test soil borings were dilled throughout this area. Fifteen borings were drilled at depths ranging between 20 and 40 feet below the existing site grades in the addition and parking garage footprints. Eight were drilled to 6.5 foot depths in future paved areas. The rest were taken below existing grades in proposed storm water management areas and in-situ infiltration testing was performed where specified by the civil engineer. As requested by the Owner, borings were located in grass areas away from pavement where possible to have as little impact on parking as possible. Two other locations specifically needed to move away from the existing building due to being within close proximity to the MRI equipment. Soil samples were classified in accordance with the Unified Soil Classification System (USCS). This project is located in the Atlantic Coastal Plain Region; where near surface natural soils consist of sedimentary materials typically with layers of granular and semi-cohesive to cohesive soils. Several borings were drilled through existing pavement areas generally 3 to 4 inches thick with another same-size layer of stone. Where encountered, topsoil at tested locations ranged from 2 to 5 inches. Findings included combinations of man-placed fill and natural soils; both of which were found in the majority of borings taken from this site. The man-made fill materials appeared to be materials placed during the construction of the existing building in 1998. This fill ranged from depths of 2 to 7.5 feet. It was not determined to have an effect on construction because the fill is similar to the on-site natural soils. The natural soils found were classified as silty sand (SM), clayey sand (SC), sandy silt (ML) and combinations of the three. The maximum column loads expected were calculated to be near 400 kips for the proposed addition. A 1” settlement has been assumed to be tolerable for this structure. Groundwater in the site was encountered at its highest level was well below grade, roughly 12’ below the lowest finished floor elevation. It was determined that dewatering systems for excavation were not necessary but would need to be monitored throughout the season so make sure of no major fluctuation that could impact construction. Building Methods Structural steel frame buildings with masonry façades are common in Prince George’s County. Alternatives were basically ruled out due to the existing building already limiting site access along with the effort taken to match the existing building type as previously discussed. Medical office buildings are not as common in the area, but there are many commercial buildings that have used similar construction methods. Because of this construction being an addition of purely medical office building uses, a basement was not necessary. The methods that were exploited reflect the current healthcare construction requirements and Kaiser Permanente’s demands as they are a very large and successful national organization. Technical Assignment1 | September 21, 2012 20 Kaiser Permanente Largo Medical Office Building Tech 1 Parking Even though there is a limited number of parking due to current construction, there is still plenty of parking available for people working construction and working or visiting the medical office building. DPR, Jacobs and members from Kaiser Permanente on site are able to park near the office trailers. There is also enough room for foremen of key trades on site to park in the same area near their site trailers as well. The rest of the construction team is able to park on the third for fourth level of the parking deck, directly west to the site. There are about 55 parking spots for craftsmen which means about half of the craftsmen are driving while half are dropped off or carpool. Parking has not been an issue mainly due to workers being able to use the new parking garage. This site has enough room for all employees and there are also two visitor spots directly beside the trailers for guest’s convenience on site. Recycling The overall goal for this project is to have at least 50% of discarded material to be recycled or reused. Monthly reports are provided summarizing the exact amounts of material being taken from site, recycled or sent to the landfill. Comingled dumpsters are used, which means any material can go in any dumpster. Once dumpsters are filled, they are removed and separated into trash or recyclables off site. A service call is placed to Lawrence Street Industry (LSI) to empty them by 5 PM the next business day. The roll-off containers allow for easy removal of material and help keep the site clean and organized. Total monthly waste varies due to various trades on site throughout construction, but more recently months have had over 25 tons removed as construction is in some of its busiest times. Even though this project isn’t striving to become LEED certified, the rights steps are certainly being taken in order to be environmentally friendly and sustainable. As of July 2012, after a year of construction, over 145 cubic yards of materials have been removed from site; with over 130 yards have been diverted. To date, less than 10% of materials have been sent to a landfill. Tipping fees are charged to the waste haulers when material is taken to a landfill. After LSI separates the trash and loads it on a truck headed for a landfill, each truck is then charged a tipping fee for the load dumped. Local Bylaws & Permits The recently built parking garage was necessary to support the increased square footage of the building as required by the Prince George’s County Zoning Ordinance. With construction of the new KP Largo Medical Office Building directly following construction of the parking garage, an interesting situation arose. The Washington Suburban Sanitary Commission (WSSC) deals with grading permits for construction projects. Donohoe Construction, the general contractor responsible for the garage, was closing out their respective work when DPR was beginning site grading for the new addition. This presented a unique situation. Typically a construction site requires one grading permit under one general contractor. The projects overlapping placed two general contractors on a single permit. In order to close out the garage and obtain the Certificate of Occupancy, a temporary permit was necessary. Fortunately, the WSSC was willing to work with closely with Donohoe Construction to help get the necessary temporary signoff for the garage with no delays. Technical Assignment1 | September 21, 2012 21 Kaiser Permanente Largo Medical Office Building Tech 1 Client Information Kaiser Permanente was founded in 1945 and has become one of the largest national healthcare organizations in the country with almost nine million people involved. Today, the organization continues to grow, providing both for-profit and not-for-profit health plans. Kaiser has hospitals and medical office buildings providing outpatient services at many locations, like the one which is the focus of this project. Outpatient services include everything a hospital does but without overnight stay. The purpose of this project is to expand and improve existing facilities to meet future healthcare demands and create an environment that improves the overall experience for the people in this facility. The real drivers on this project are schedule and cost. The schedule has been tight from the very beginning of construction. First Patient is the most critical milestone, scheduled for July 17, 2013, and cannot be missed. Planning for the renovation is currently underway and expected to begin full swing upon completion of the addition. DPR has worked with Kaiser Permanente in the past and projects have been very successful. Due to DPR’s past successes, it can be said that quality and safety must never be compromised throughout construction, regardless of how challenging a project may be. Kaiser Permanente has their own set of standards that clearly define goals and expectations, making it evident that KP has very high anticipations for their facilities. Cost is closely monitored, as evident by the weekly change order meeting that take place. Also, several bulletins and construction change directives (CCD’s) have been issued since the start of construction. It’s understood by all parties involved that construction needs to keep moving in order to reach the First Patient milestone. Kaiser works closely with DPR to track work being put in place and to make sure appropriate payments are made for that work. Having minimal impact on the current functions of the existing building is expected to make the renovation very challenging. KP wants the building to remain occupied throughout construction; therefore, a phased renovation will be required. Work is being planned to place on multiple floors at a time in small areas. Because the whole building is to remain occupied, night work is going to be required. Shifts will have to set up and tear down equipment daily; therefore, four 10-hour shifts are going to be utilized instead of five 8-hour shifts weekly. Efficiency was the key driver for this decision as there will be less time preparing to work or cleaning up. KP expects their employees to be able to continue their work without having to avoid construction areas (except for those departments closed down for full renovation). Zip walls will be used to contain dust and debris while making for easy cleanup. Project Delivery System Kaiser Permanente has chosen a design-bid-build project delivery for the construction of this 3-story addition and renovation work. Having a clear vision in mind what a successful end product should be, this delivery method made the most sense as design function and layout were basically predetermined once demand for expansion was discovered. An organizational chart including contract types listed with appropriate project team members has been created. It can be found in Appendix E. Technical Assignment1 | September 21, 2012 22 Kaiser Permanente Largo Medical Office Building Tech 1 DPR has been awarded a guaranteed maximum price (GMP) contract as the general contractor. With that, DPR takes on risk for all of the subcontractors on site. All of the contracts DPR holds with subcontractors are lump sum contracts. Drywall and framing is the only activity that DPR self-performs. DPR is not contractually tied to the construction manager, Jacobs, or the architect. Essex Construction has a lump sum contract agreement with DPR. Essex is a minority business (MBE) and team members help with project management; including directly managing the electric/fire alarm sub. Pro-Air is the only subcontractor to hold another contract, as sheet metal work has been awarded to CMC. Ellerbe Becket has an interesting contract with KP, a term contract. Qualified firms were able to apply when Kaiser announced the opportunity. Upon being awarded the contract, Ellerbe Becket is now contractually tied with Kaiser for a fixed period of time. Duration and cost of this contract were not deemed necessary. What’s also interesting is Ellerbe Becket performs more than just the aesthetic design. Structural, mechanical, electrical, plumbing, and interiors are all engineered and designed in house. The only outside assistance is required from a civil engineering firm and a landscape architect, both of which are lump sum contracts. Jacobs, the construction manager has a professional services agreement with a fixed fee. Bonds and insurances are required by KP. A performance and payment bond, commercial general liability and subcontractor default insurance are all included in the project budget. Builder’s risk insurance has been provided by the owner. A 3% construction contingency has been included in the GMP. Staffing Plan A staffing chart making up DPR’s project team can be found in Appendix E. The staffing chart is actually shown as a plan view of the office trailer showing members’ areas to emphasize the encouragement of collaboration. The field office staff includes the coordinator (FOC), two superintendents, Jeff Busch and Tim Miner, and the project managers, John Stull and Michael Hudak. Blake Haldeman and Emily Price were project engineers. Matt Hedrick was the BIM Champion and took over as a Project Engineer when Emily Price left on maternity leave. A safety person for the region, Stephen Cloutier, is on site a few times a week. The project executive, John Anania, is on site as required. Two members from Essex Construction are also in the trailer; Joe Brito is responsible for quality control and Anthony Moore manages the electric subcontractor and assisted DPR’s management staff.
